There's usually a minimum charge for all those services. You've probably been hit by that. Can't avoid VAT you will (should) pay it wherever you buy from.
We used to bring in complete 40 ft container loads from the Far East about ten years ago and it cost about £2000 all in (plus VAT which we got back as we were registered) so there is a definite advantage if you can fill at least a 20 ft container or share it with others.
